Lead on Surfaces

The examination of Lead on Surfaces is conducted using wipe samples. This Dust/Wipe category of environmental lead investigations often is employed to establish baseline conditions of surfaces as well as to establish clearance criteria after an abatement activity.

AIHA and others have promulgated strict field sampling protocols. Results are viable only when the samples are collected on certain wipe material approved by EPA. The submittal of field blanks are also required for this method. (See FAQ) Results are reported in micrograms of lead per unit area sampled on the surface (ex: ug/ft2). Primarily, accreditation and proficiencies are through AIHA.
